Title: Process and device for the positioning of a sensor apparatus
Inventor: KIPPHAN HELMUT
IPC: B41F33/00
Filed: 1991-04-03
Abstract: ABSTRACT          The  invention refers to a process  for the positioning  of  a measuring field of a sensor apparatus to a selected region on the outer cylindrical surface of a cylinder in a rotary printing press, as well as to a device to execute this process. The process and the device, according to the invention, serve to select a suitable measuring field on the cylinder, and to position a sensor apparatus on the selected field. This poses a problem when the measuring apparatus  is too close to the cylinder or too far from the cylinder, or when the wave length of the measuring light lies in the invisible portion of the spectrum.          To solve the problem it is proposed to direct the light spot (31) of a pilot light source (21) into the selected region, to store the position of this light spot (31) on the outer surface of the cylinder in a computing/control apparatus,  and to control the sensor apparatus in such manner that it supplies measured data from the selected region.

Title: Improved process for producing a high total dietary corn fiber
Inventor: GEISFELDT J E TODD
IPC: A23L5/20
Filed: 1991-05-01
Abstract: An improved process is disclosed for producing corn fiber having a high total dietary fiber content and a reduced SO2 content. A dilute aqueous slurry of the corn fiber obtained from the corn wet-milling process is separated by means of a hydroclone to give a fiber fraction of enhanced total dietary fiber content.    This fiber fraction is then passed into a first centrifugal paddle screen followed by two stages of washing, including washing with a second centrifugal paddle screen. Fiber from the second centrifugal paddle screen, which is optionally pressed to remove water that contains dissolved SO2, is dried to make the final product. Heated water can be used during washing to remove additional SO2 more effectively.

Title: Method and apparatus for optimizing fuel-to-air ratio in the combustible gas supply of a radiant burner
Inventor: CLARK DANIEL R
IPC: F23N5/08
Filed: 1991-05-30
Abstract: A method and apparatus to optimize the proportion of gaseous fuel and air supplied to a radiant burner employed in a heating appliance. With the flow rate of the gaseous fuel supply held constant, the flow rate of the air supply is adjusted to change the relative proportion of air and fuel in the mixture to attain an optimum value far burner combustion, i.e. a vague where the proportion of air is slightly greater than the stoichiometric ratio. The invention employs a sensor to measure the intensity of the radiation emitted by the burner while the the air supply to the burner is varied. From the measurements obtained, control parameters are derived which are then applied to set the air supply flow rate to a level that results in the optimum proportion of air and fuel in the mixture.

Abstract: Abstract The device comprises a draw-in member for the warp yarns, a reed hook (22) for opening the particular reed gap for the draw-in member with the warp yarn and transport means for the stepwise transport of the weaving reed in its longitudinal direction. These transport means have a first transport member (BW) extending over the length of the weaving reed and coupled to this in the operating  state  and  a  gripper-like  second  transport member (48, 49), the second transport member (48, 49) being provided for intermittent engagement with the first transport member (BW).        As a result of this solution, the two functions of reed transport and reed opening are decoupled and can each be optimised independently. This allows the draw-in frequency to be increased. Moreover, the reed hook and reed teeth are given maximum protection.                                                  Figure 4

Title: Johnson's electro heating pad
Inventor: SAMUEL JOHNSON
IPC: H05B3/36
Filed: 1992-04-24
Abstract: Abstract JOHNSON'S ELECTRO HEATING PAD   From the very beginning, Heat treatment has been a time honored means of obtaining relief from physical pain in conjunction with medicine.          Yet, pain will remain pain , but the search for new and better techniques of heat applications continue.  Previously we used hot water bottles for fomentation. Moving with the times, in the mid 70's Sunbeam a company came up with a product better known as the Electric Heating Pad,  which has an element with an adjustable switch that has three levels of temperatures. This pad is in the form of a belt that can be strapped on to areas where it is to be applied. but the pad's temperatures; are sufficiently high to cause burns, regardless of the control switch, so the pad has to be frequently removed from the skin to avoid burns. This is due to the thermostat which is built in to the pad. In the thermostat, there are two metal strips, which when in contact,  conduct electric current which heats the element, and resulting in heating the pad. The greatest danger is any kind of pressure could trigger the two metal strips and could burn the user seriously.  Especially if He/She goes to sleep or for some reasons is unable to get to the control switch or unstrap the pad.            At that moment in time Sunbeam's Electric Heating  Pad was a break through to treat patients suffering from orthopaedic ailments. But in time it has proven that Sunbeam Electric Heating Pad is not the safest device for fomentation it is in fact quite dangerous, and needs constant supervision.          A new concept has been introduced by a similar product. Johnson's electro Heating Pad is designed with modern technology to operate at a regulated temperature for fomentation. It can be used for more than 24 hours at a stretch, without getting a burn. It is made of an heating element, felt, felt padding, enclosed in a rexine case with high frequency sealing. It is about half an inch in thickness and is extremely flexible, which allows it to take the shape of the body part easily. The heat of the pad can be controlled by a switch that has three levels of temperatures (high, medium, and low). There is no thermostat in Johnson's Electro Pad therefore there is no danger of getting burnt.

Abstract: RD-20,854 IMPROVED STARTING CIRCUIT FOR AN ELECTRODELESS HIGH INTENSITY DISCHARGE       LAMP                           Abstract A passive starting circuit for an electrodeless HID lamp includes a series resonant LC circuit including an inductor of variable impedance coupled in series with the parasitic capacitance between a starting probe and the excitation coil of the lamp, and further including a coupling capacitance for directly coupling the starting circuit to the excitation coil.  The coupling capacitance is connected between the high terminal of the excitation coil, or a point in the circuit at approximately the same potential thereof, and a conductive support for holding the lamp and starting probe in a lamp fixture.  In this way, the starting voltage is maximized for more efficient and rapid starting. Preferably, the series resonant capacitance of the starting circuit is optimized so that the ballast requires little, if any, retuning after the lamp has started.

Patent CA-2074761-A1 (CA)
Inventor: GILL WILLIAM A
IPC: C08G18/66
Filed: 1992-07-28
Abstract: It has been discovered that a particular polyurethane formulation may be used to prepare "pour-in-place" (PIP) polyurethane foam articles where the formulation is injected into a mold bearing an exterior covering such as a fabric without the foaming liquid striking through the layer. The formulation employs a hydrophilic polyhydric compound to help the reactivity balance that minimizes penetration of the exterior covering while also stabilizing the rising foam against shear collapse without excessively tightening the foam. Contrary to the conventional expectation that the hydrophilic polyhydric compound would, cause strike through problems since it delays the initial reaction time, it has been found to have the noted stabilizing effect. A preferred hydrophilic polyhydric compound is glycerine. A preferred isocyanate for the formulation is tolylene diisocyanate (TDI), in contrast to diphenylmethane diisocyanate (MDI) heretofore used in PIP foams.
